The Carter BBD carburetors were not stamped with the carburetor number. They were manufactured with an ID tag only which included the Carter carb number. We have broken down the BBD models so you can identify the rebuild kit based on accelerator pump style.
WE CAN NOT IDENTIFY A REBUILD KIT BY THE EXTERIOR OF THE CARBURETOR
